An object of this invention is to rovide a simpler and more efiicient means or conveyinga. lubricant to the valves and to the up er portion of the cylinders-of an inter- 5 na combustion engine.

This and other objects, as w1ll hereinafter appear, are accomplished by this invention which is fully described in the following specification and shown in the accompanying drawing, in which the figure 1s a longitudinal vertical section through a lubricating device and showing rather sketchily its connection with an intake manifold 'ofan internal combustion engine of an automobile.

The embodiment illustrated comprises a container 10 adapted to hold lubricating oil,

' this container belng preferably of glass and being sealed within a metal cap 11 as by 29 means of cement 12. The cap 12 communi- ,cfat'es through a tube 13 with a T-connection 14 which is screwed into an intake manifold 15 of an automobile engine.

The run of the T 14 connects through a pipe 16 with the top of a vacuum feed tank 17 in a well known manner. The tube 13 is secured in a suitable connection 18 by means of a threaded plug 19, the connection 18 being secured into the side of a cap 11 and having an orifice 20 drilled or otherwise formed therein. This hole I have found to be about .04 to .06 inches in diameter for the best results.

The cap 11 is preferably secured to the dash A and is provided at. its upper portion with an opening which-is screw-threaded to receive a plug 21 which serves normally to close the opening. Through this a suitable lubricating oil B is poured, and should be 40 maintained near the lever as shown.

- A pipe 22 dips into this oil, and this pipe is carried by the cap 11, the pipe 22 communicating with the atmosphere through an opening in the fitting 23. Between these two is placed an orifice 24 which should be some what smaller than the orifice 20, preferably .02 to .03 inches. The fitting 23 is screwthreaded to receive a tapered plug 25 which is provided along one side with a notch 26. By screwing the plug 25 in and out, the effective opening for air' into the fitting 23 is adjusted, the air in this case passing through the groove 26, thence between thetapered end of the plug 25 and its tapered seat. I

It will be seen that with the engine in operation, vacuum in the intake manifold 15 will cause air to flow past the plug 25 down through the pipe 22, this air then bubbling up through the lubricating oil A and thence out through the tube 13 to the intake manifold 15 of the engine. As the air passes through the lubricating oil A, some of theoil becomes. entrained and passes out in the form of minute droplets through the tube 18 and thence past the intake valves into the upper portion of the engine cylinder. The oil thus entrained is carried into the c linder to a point where lubrication is neede' Actual experiments have shown that the particular arrangement of orifices and of the adjusting plug member 25 rovides a very excellent means for controlling the amount of lubricant thus fed to the upper portion of the cylinders and to the valves therein. Should the plug 25 become displaced, the orifices will prevent an excess of oil from being fed.

While I have shown and described but a single embodiment of my invention, it is to be understood that it is capable of many modifications. Changes, therefore, in the construction and arrangement may be made which do not depart from the spirit and scope of the invention as covered by the appended claims.

1. In a lubricating device for internal combustion engines, a container for lubricating oil, an intake pipe terminating near the bottom of said container, means for regulating the flow of air through said pipe, a tube connecting the upper portion ofsaid container with the intake of an internal combustion engine, and a restriction in said ipe'and tube for limiting the flow of air, t e crosssectional area of the restriction in the pipe being larger than that of the restriction in the tube.

2. In a lubricating device for internal com- 9 bustion engines, a container for lubricating oil, an intake pipe terminating near the bottom of said container, means for regulating the flow of air through said pipe, a tube connecting the upper portion of said container with the intake of an internal combustion engine, and a restriction in said pi e and tube for limitin the flow of air, t e cross-sectional area 0 the restriction in the pipe being substantially four times that of the restriction in the tube.

3. In a lubricating device for internal combustion engines, a container for lubricating oil, an intake pipe terminating near the bottom of said container, means for regulating the flow of air through said pipe, a tube connecting the upper portion of said container with the intake of an internal combustion engine, and a restriction in said pine and tube for limitin the flow of air, the cross-sectional area 0% the restriction in the pipe being larger than that of the restriction in the tube, the diameter of the restriction in the tube being substantially .025 inches.

In testimony whereof, I have hereunto set my hand and aifixed my seal this 16th day of November, 1928.
